IMPROVEMENT IN PASSENGER-CAR VENTILATORS.

Specification forming part of Letters Patent N 0. 181,499, dated August22, 1876; application filed January 15, 1876.

To all whom it may concern:

Be it known that I, WASHINGTON FOGLE- SONG, of Dayton, Montgomerycounty, State of Ohio, have invented an Improvement in VentilatingApparatus for Passenger-Oars, of which the following is a specification:

My invention relates to the manner of introducing fresh air to theinterior of a passenger-car, to the exclusion of all other kinds, by acertain connection of pipes or conducting-tubes, which lead from a pointin front of the smoke-stack of the engine directly into thepassenger-cars, and into the cars only, so that the speed of the trainwill keep up such a current of air in these pipes leading to thecarsthat there will be a compressed state of vatmosphere in said carsthat will effectually prevent the entrance of any particles of impureair that may envelop the train when the doors and windows ofthe cars areopened casually.

My invention consists in incasing the ordinary ventilating-roof of arailroad-car, said casing forming the fresh-air conductor. Inconsequence of this construction the ventilating-roof is utilized, andmy invention may be readily applied to all ordinary railroad-cars.

Figure l is an elevation of a train of cars, showing my improvement andthe passengercar to which it connects in section. Fig. 2 is aperspective view of the forward end of the conducting-pipes. Fig. 3 is aperspective view of the top end of a passenger-car having my improvedventilator attached. 7 LetA represent one of the coaches of apassenger-train, and B the locomotive. The car A is of ordinaryconstruction, having the raised ventilating-roof a and apertures a".Formed over the roof proper, and around the ventilating -roof at, is aconducting compartment or chamber, 0, which makes up part of my tlues Gleading from the front of the train to the interior of the coaches, andhaving contracted mouths c at the ends of the car, which are fitted withsuitable valves 0, for governing the action of the compartment.

Attached to the tender of the locomotive is a conducting compartment orchamber, D, and attached to the locomotive is also a conducting-chamber,E, which, however, branches out from a central position on the cab intwo pipes, e 6, past each side of the smoke-stack, and these pipes areprovided with enlarged months 0 c, to readily engulf the adjacent air asthe train rushes forward. To connect these pipes together, and form onecontinuous pipe of them, I provide the flexible connections F of leatheror kindred material, secured in any desirable and adjustable manner,which connection will accommodate itself to themrying distance apart ofthe cars in backing and moving forward.

The current of air in the pipe 0 DE 6 0 caused by the movingtrain rushesback from the mouths 6 0', along the roofs of the coaches, and entersthe apertures a in the roofs a, and into these apertures only, as thevalve 0 ot'the back end of the last compartnient O is closed purposely.

Now, it is evident that the current of air brought'from the front end ofthe train will be pure and wholesome, and if the coaches do notfurnishmeans of exit through doors and windows, 860., large enough, the currentof air from the apertures a will cause a compressed state of atmospherein the car, which will preclude the possibility of impure air to enterthe car when doors, 860., are opened casually.

It is evident that the form of conductingpipe shown in the drawing isnot requisite in all cases, as the parts 0 c a can be built in thecoaches in any desired form, and the pipes D and E can be variouslyformed.

Having thus described my invention, I

claim Thecombination, with a railroad-car, of the casing covering theordinary ventilating-roof thereof, and adapted to be connected with apipe or pipes extending to the front of a locomotive, for supplying thecar .With pure air when running in a train, substantially as specified.

In testimony of which invention I hereunto set my hand.
